Abstract

Purpose

Soil salinization severely hinders the development of agriculture. Pristine biochar (BC) has a considerable impact on improving soil quality and maximizing crop yield. However, applying biochar has the risk of aggravating soil salinization. Acid-modified biochar may have a good effect on the improvement of saline-alkali soil.

Methods

Nitric acid and phosphoric acid were used to modify the pristine biochar (BC). The pristine biochar (BC), nitric acid-modified biochar (NC) and phosphoric acid-modified biochar (PC) were used at 1%, 2%, and 3% (w/w), respectively. There were ten treatments in total: CK, BC1, BC2, BC3, NC1, NC2, NC3, PC1, PC2, and PC3.

Results

Our results indicated that the application of biochar further aggravated soil salinization. Soil pH and EC significantly increased by 0.08–0.42 units and 215.51–362.07 μS.cm−1, respectively. Additionally, the BC application reduced the activities of C-, N- and P-acquiring enzymes in saline-alkali soil. Compared with BC, NC and PC decreased the alkaline metal elements by 84.34% and 79.29%, respectively, and enhanced the specific surface area. Acid-modified biochar significantly reduced the content of Na+, Cl, SO42−, CO32− and HCO3. Meanwhile, the application of acid-modified biochar reduced soil pH and EC by 0.16–0.59 units, 228.38–788.93 μS.cm−1, respectively. Furthermore, the application of acid-modified biochar enhanced N fixation ability and the activity of C-acquiring enzymes and P-acquiring enzymes.

Conclusions

The application of pristine cotton straw biochar will further aggravate soil salinization, thereby inhibiting the soil enzyme activities. In contrast, acid-modified cotton straw biochar can reduce soil salinity, improve soil available nutrients and also enhance the enzymatic activities, which is advantageous to the restoration of saline-alkali soil.

酸改性棉秆生物炭对改良盐碱地具有指导意义
目的土壤盐碱化严重阻碍了农业的发展。纯净的生物炭(BC)对改善土壤质量和最大限度地提高作物产量有很大影响。然而,施用生物炭有可能加剧土壤盐碱化。方法用硝酸和磷酸对原始生物炭(BC)进行改性。原始生物炭(BC)、硝酸改性生物炭(NC)和磷酸改性生物炭(PC)的使用浓度分别为 1%、2% 和 3%(重量比)。结果表明,施用生物炭进一步加剧了土壤盐碱化。土壤 pH 值和 EC 值分别明显增加了 0.08-0.42 个单位和 215.51-362.07 μS.cm-1。此外,施用 BC 还降低了盐碱地中 C、N 和 P 获取酶的活性。与 BC 相比,NC 和 PC 分别减少了 84.34% 和 79.29% 的碱金属元素,并增加了比表面积。酸改性生物炭显著降低了 Na+、Cl-、SO42-、CO32- 和 HCO3-的含量。同时,施用酸改性生物炭后,土壤 pH 值和 EC 值分别降低了 0.16-0.59 个单位、228.38-788.93 μS.cm-1。结论原生棉秆生物炭的施用会进一步加剧土壤盐碱化,从而抑制土壤酶的活性。相比之下,酸改性棉秆生物炭能降低土壤盐渍化程度,提高土壤可利用养分,还能增强酶的活性,有利于盐碱地的修复。

期刊介绍: The Journal of Soils and Sediments (JSS) is devoted to soils and sediments; it deals with contaminated, intact and disturbed soils and sediments. JSS explores both the common aspects and the differences between these two environmental compartments. Inter-linkages at the catchment scale and with the Earth’s system (inter-compartment) are an important topic in JSS. The range of research coverage includes the effects of disturbances and contamination; research, strategies and technologies for prediction, prevention, and protection; identification and characterization; treatment, remediation and reuse; risk assessment and management; creation and implementation of quality standards; international regulation and legislation.
